The monitoring network on this water
Hydrionis holds 1,568 values from 2 gauges on this water. Discharge is a property of a gauge and its reach, not of this water as a whole, so this page reports the network and its records rather than a single figure.
Every gauge Hydrionis holds here

What this record holds
Hydrionis decides which waters get a page, and which of those are offered to search, from what is actually held rather than from how the page reads. Five signals are counted; this record has 3 of them, which makes it a full profile.
| Signal | Held | Counts |
|---|---|---|
| Gauges holding a real record | 2 | no |
| Years spanned | 65 | yes, 20 or more |
| Values held | 1,568 | yes, 1000 or more |
| Distinct measurements | 2 | yes, 2 or more |
| Publishers measuring it | 1 | no |
| Official identifiers | 0 | recorded, not counted |
Where these figures come from
Source: EA — Hydrology Data Explorer API, EA measure 54d2b82b-cd8a-4fae-bde4-c11d9fb80af7-flow-m-86400-m3s-qualified. Licence: Open — attribution required (attribution required).
Method: Mean of the twelve monthly means for the year. Computed from months rather than from daily readings directly, so that a year with uneven observation is not weighted toward its best-observed months. Years with any month missing are not published.
Aggregated by Hydrionis from daily mean flow published by the Environment Agency under the Open Government Licence v3.0.
